[CRIU] CRIU and QEMU/KVM

[Andres Toomsalu]

KVM/QEMU has ofcourse checkpointing for live migration - but I cant find anything suitable for continuous non-blocking checkpointing - Kemari supposed to do that but it seems to be abandoned and I cant find any further developments on that regard. DMTCP allegedly could do this with the help of plugin utilizing KVM kernel driver API - so why not also CRIU in theory (eg cant it be added - what is the blocking issue/design)? There is a publication describing DMTCP approach in detail:  http://arxiv.org/pdf/1212.1787v1.pdf

Having kind of hypervisor agnostic checkpointing/restore package would be a great opportunity to build homogeneous cloud HA services around it.

Kind regards,
